Superheavy elements, also known as transactinide elements, transactinides, or super-heavy elements, or superheavies for short, are the chemical elements with atomic number greater than 104. [1] The superheavy elements are those beyond the actinides in the periodic table; the last actinide is lawrencium (atomic number 103).
Because the produced nuclei underwent alpha decay rather than fission, and the half-lives were several orders of magnitude longer than those previously predicted [l] or observed for superheavy elements, [57] this event was seen as a "textbook example" of a decay chain characteristic of the island of stability, providing strong evidence for the ...
Transuranic elements may be used to synthesize superheavy elements. [7] Elements of the island of stability have potentially important military applications, including the development of compact nuclear weapons. [8] The potential everyday applications are vast; americium is used in devices such as smoke detectors and spectrometers. [9] [10]
Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium ...
Science teachers will soon be instructing their pupils to buy new textbooks or crudely add four new elements to their copy of the periodic table. The chemical substances known as 113, 115, 117 and ...
In comparison, only platinum is known to show the maximum oxidation state in the group, +6, while the most stable state is +2 for both nickel and palladium. It is further expected that the maximum oxidation states of elements from bohrium (element 107) to darmstadtium (element 110) may be stable in the gas phase but not in aqueous solution. [3]

Tennessine may be located in the "island of stability", a concept that explains why some superheavy elements are more stable despite an overall trend of decreasing stability for elements beyond bismuth on the periodic table. The synthesized tennessine atoms have lasted tens and hundreds of milliseconds.
